Had some tests on a XPS 15 9550 as well. With identical kernel and firmware, cannot reproduce this issue so far. All the seem related error messages also appear in the healthy one, the firmware has stayed as it is currently since 2015, and verified bionic/focal installed the same blob. Also tried upgrading it from Bionic to Focal, yet still cannot reproduce it even under a 100 run stress test.
Someone[1] reported that it could be a bug in NetworkManager that it tries to reuse a misconfigured connection, and simply delete that and reconnect will do: NetworkManager[767]: <info> [1591110830.1613] device (wlp2s0): state change: need-auth -> failed (reason 'no-secrets', sys-iface-state: 'managed') So maybe you would like to try find the connection in WiFi settings, click "Forget Connection" in its own settings page. Maybe even remove all the remembered connections as well.
